EGG CANDLER.

Application filed December 29. 1924. Serial No.'758,555.

This invention has to do with an egg candler, and more particularly with certain features of its construction whereby the light is properly confined for most effective use.

It is customary to employ egg candlers in a dark room, each operator working with as many as five cases at one time. As the eggs are candled, they are sorted and deposited in the different cases. It is a prob lem always to provide the requisite light for candling and at the same time illuminate sufficiently the cases into which the eggs are placed. The filling of the cases cannot proceed without some light, as otherwise the operators would be unable to determine whether or not every filler was full before proceeding with a new layer of eggs.

According to my invention, the Candler, which is preferably electrically illuminated, is provided with a front hole or opening before which the egg is placed for observation. It is also provided with flaring side walls which reflect a small quantity of light downwardly onto the several cases which are to be filled. In addition the walls of the candler are so configured as to confine this light to just the area where the operations are carried on. By the use of such a construction, an operator is enabled to more accurately grade and fill the cases, also to nail covers thereto at the required time.

An exemplification of this invention is set forth in the drawing in the manner following:

Figure 1 is a plan view of the candler in its relation to several cases wherein the eggs are to be deposited after sorting;

Fig. 2 is a front elevation thereof with a portion of the near wall broken away; and

Fig. 3 is a transverse section on line 33 of Fig. 2.

It should he noted at the outset that the Candler, herein designated as A, is mounted in position above a plurality of egg cases B. These may be arranged 1n the order shown in Fig. 1, live being a convenient number for.

a single operator to look after at one time.

The candler proper may conveniently be formed of sheet metal, and, as shown, coinprises a casing having a horizontal top wall 5, a vertical rear wall 6, two outwardly flaring side walls 7 and a front wall composed of inwardly extending flanges 8 connected by an outwardly bowed door 9. This door may conveniently be hinged as at 10 to one of the flanges and with the aid of a pin 11 or other suitable device is locked also to the other flange.

The casing is open on its bottom. In the bowed door is an opening 12 through which shows light from an electric bulb 13 mounted Within the device. The candling operations are carried on in front of the opening 12, and, with the aid of light directed downwardly from the casing, a proper and accurat?l filling of the cases may be proceeded wit Among other advantages which inhere in my invention is the simplicity of its construction. The electric bulb, which is of the conventional kind, may be screwed into a socket 14 to which an electrical conductor 15 is connected. This socket is entered through a hole 16 in the top wall of the casing, and, if desired, may connect therewith in such a manner as to afford support for the casing.

In candling eggs it is necessary that the observation opening be spaced from the light for an appreciable distance. By so do ing, a better test may be made without subjecting the egg to excessive heat. Such requirements as these are fully met in the present construction by the employment of an outwardly bowed or convex door, of the kind described. The front wall which is characterized both by such adoor and by other flanges which are recessed from the observation opening is well calculated to reduce the amount of light which will be directed from the casing upon the egg cases therebelow. It is largely because of the particular location and disposition of the casing walls, as hereinbefore described, that I am able to secure a proper degree of working light 011 the cases, and nowhere else.

A further detail of construction should also be noted. This is the door which may be opened up at the conclusion of the candling operations or at any other time. -With the door wide open a flood of light is released from the front for assistance in clean ing up, or in gathering of materials, or for any other purpose. It is accordingly unnecessary to alter the position of the candler, but only of the door thereof, when additional light is desired.

I claim:

In an egg candler, the combination of a casing enclosed on all sides except the hot- I tom and having a vertical back wall, clownwardly flaring side walls, vertically disposed inwardly extending front flanges connected to the side walls, an outwardly bowed front wall extending between the two flanges having a hinged connection with one and a releasable connection with the other, there being an opening in the front wall at a point farthest removed from the back wall,

and an illuminant depending into the easing from the top thereof and disposed relative to the flaring side walls and front opening, respectively, in such manner as to re fiect the light downwardly from the casing while occupying a proper test position for an egg which is held before the front open-- ing, substantially as described.
